Welcome to Hebei Speed Torque Transmission Technology Co., Ltd. – Your trusted partner for high-performance power transmission solutions. As a factory-direct manufacturer with over 7 years of experience, we proudly present our Universal Coupling, engineered for flexible compensation, stable transmission, and all-round heavy duty performance. This coupling is the ideal choice for industries requiring reliable torque transfer under harsh conditions, offering unmatched durability and precision. Whether you need to connect misaligned shafts or handle shock loads, our product ensures smooth operation and extended equipment life.
Key Features & Technical Specifications
Our universal coupling is designed to excel in demanding applications, providing exceptional misalignment compensation (angular, parallel, and axial) while maintaining constant velocity rotation. The robust construction uses high-grade alloy steel or optional stainless steel, heat-treated for maximum strength and wear resistance. Below are the core specifications:
| Parameter | Value / Range | Benefits |
| Torque Capacity | 100 – 50,000 Nm (customizable) | Handles heavy shock loads without failure |
| Angular Misalignment | Up to ±5° | Compensates installation errors and shaft deflection |
| Axial Movement | ±3 mm (depends on size) | Accommodates thermal expansion and shaft end float |
| Speed Range | Up to 4000 RPM (depending on size) | Suitable for high-speed rotating equipment |
| Bore Diameter | 20 – 200 mm (custom sizes available) | Versatile fit for various shaft sizes |
| Lubrication | Pre-greased, maintenance-free options | Reduces downtime and service costs |
Advantages & Customer Benefits
Factory Direct Pricing – Eliminate middlemen, save up to 30% compared to distributors.
Flexible Compensation – Allows angular, parallel, and axial misalignment, protecting bearings and seals from premature wear.
Stable Transmission – Precision-machined components ensure constant velocity even under varying loads, reducing vibration and noise.
All-Round Heavy Duty – Reinforced yoke and cross block design withstand extreme torque and impact, ideal for mining, steel, and construction equipment.
Customizable Options – Bore, keyway, length, and material can be tailored to your specific application (available upon request).
Easy Installation – Standard flanged or splined connections simplify assembly, no special tools required.
Long Service Life – Heat-treated alloy steel with durable surface coating resists corrosion and fatigue.
Frequently Asked Questions (FAQ)
Q1: What is the maximum misalignment this coupling can compensate for?
A: Our universal coupling can handle angular misalignment up to ±5°, parallel offset up to 2mm (depending on model), and axial movement up to ±3mm. For extreme cases, custom designs are available.
Q2: Is the coupling maintenance-free?
A: Standard versions are pre-lubricated with high-temperature grease and sealed, requiring no regular lubrication. For heavy-duty continuous operation, optional relubrication ports can be added.
Q3: Can I use this coupling for reversing applications?
A: Yes, the symmetrical design allows smooth bidirectional rotation with minimal backlash, making it suitable for reversing drives.
Q4: What materials are available?
A: The standard material is 40Cr alloy steel (quenched and tempered). For corrosive environments, stainless steel (304 or 316) is optional. Surface treatments include phosphating, black oxide, or zinc plating.
Q5: How do I select the right size for my application?
A: Provide us with the shaft diameters, torque requirements, operating speed, and misalignment angles. Our engineering team will recommend the optimal model or create a custom design.
Q6: Do you provide samples for testing?
A: Yes, we offer sample orders for evaluation. Lead time for standard samples is 7-15 days. Please contact our sales team with your requirements.
Q7: What is the typical delivery time for bulk orders?
A: For standard sizes, production takes 15-20 working days after deposit. Customized orders may require 25-35 working days, depending on complexity.
Q8: How do you ensure product quality?
A: Our factory is ISO9001 certified. Every coupling undergoes material inspection, dimensional check, and torque test before shipment. We also offer third-party inspection upon request.
